ELI5: Explain Like I'm 5

Information card

An information card is like a small identity card that tells people some basic information about you. You might use one when you go to the doctor's office, for example. Your card would have your name on it, your age, maybe your height and weight, and some other important details like any allergies or medications you take. The card helps the doctor get a quick sense of who you are and what your health needs are. It's kind of like a shortcut to important information so everyone can get what they need quickly and easily.
